Roof Replacement Cost in Idaho (2026)

Up-to-date 2026 prices per square and per home, plus the local code and climate factors that move your bid.

Quick answer: A new asphalt shingle roof in Idaho costs about $10,500 – $15,000 for a typical 25-square roof (about 2,500 sq ft of roof surface), or $420 – $600 per square installed with tear-off. Standing-seam metal runs $840 – $1,300 per square.

What the data says about roofing in Idaho

BLS counts about 1,070 roofers working in Idaho, with a mean wage of $24.18 an hour — 12% below the US mean of $27.44. Construction laborers, who handle tear-off and clean-up, average $22.41 (9% below the US). At median wages a four-person crew (three roofers and a laborer) costs about $91.24 an hour in pay alone, before the contractor's insurance, overhead and margin.

On the materials side, BEA puts Idaho's price level for goods at 96.3 against a US figure of 99.6, so shingles, underlayment and flashing run about 3% below the national average. Labor moves the Idaho price more than materials do, so comparing several itemised bids is where the savings are. Overall Idaho ranks 19 of 50 from cheapest to most expensive on this index (combined factor 0.928).

How the Idaho prices are calculated

1. Start from our national installed prices per square: $450–$650 architectural shingles, $900–$1,400 metal, $1,200–$1,800 tile.
2. Labor share: about 45% of an asphalt job (our labor cost per square figures), materials the other 55%.
3. Labor index = Idaho roofer mean wage ÷ US mean = $24.18 ÷ $27.44 = 0.881.
4. Materials index = goods RPP ÷ US goods RPP = 96.3 ÷ 99.6 = 0.967.
5. State factor = 0.45 × 0.881 + 0.55 × 0.967 = 0.928, applied to each national band and rounded to $10: $420–$600/sq shingles, $840–$1300 metal, $1110–$1670 tile.

Cost for a typical Idaho home

For a 2,000 sq ft single-family home (≈ 20 roofing squares with average pitch and waste), expect:

• Asphalt (architectural): $8,400 – $12,000
• Standing-seam metal: $16,800 – $26,000
• Concrete or clay tile: $22,200 – $33,400
• Permit fees: about $125–$325 (check your local building department)

Planning estimate — actual quotes vary

New roof cost by house size in Idaho

Squares assume a 6/12 pitch and 10% waste. A one-storey house has a roof footprint about equal to its floor area; a two-storey house of the same floor area has roughly half the footprint, so half the roof. Steeper roofs, dormers and a second tear-off layer push the figure up.

Roof replacement cost in smaller Idaho towns

Most searches for a town-level price — a small town or a county seat in Idaho — land on the state range above, because local quotes are built from the same three things everywhere: the roof's size in squares, the material, and the local labour rate. Rural and small-town crews often quote toward the lower half of the Idaho range; jobs that need a long drive, steep terrain, staging or a dumpster on a tight lot quote toward the top. Where we publish a city page below, it applies a local multiplier to the state baseline.

Work out your own roof price

1. Measure the house footprint to the outside of the eaves (length × width for each rectangle) and add the pieces.
2. Multiply by the pitch factor for your roof (1.118 for 6/12; the roof pitch chart lists every pitch) to get the sloped roof area.
3. Add 10% for waste on a simple gable, 15% on a hip roof, then divide by 100 to get squares.
4. Multiply the squares by $420 – $600 for architectural shingles in Idaho, and add the permit (about $200).

Measure with the roof area calculator, look up your pitch factor on the roof pitch chart, or let the project estimator do all four steps. For an installed price by material from your house size and pitch, use the roof replacement cost calculator, and compare every state on the national roof cost per square foot table.

What drives roofing cost in Idaho

Cold-weather underlayment recommended above 4,000 ft elevation. On top of that, the same factors that move every roof bid apply: pitch, tear-off layers, deck repair, ventilation upgrades, and accessibility.

Code and climate rules that affect a Idaho roof

• In Idaho's colder and higher-elevation areas, the local climate table that goes with the IRC (Table R301.2) marks ice-barrier underlayment as required. Where it is, a self-adhering membrane must run from the eave edge to at least 24 in inside the exterior wall line (IRC R905.1.2) — on most houses one or two courses along every eave, which shows up as its own line on the bid.
• Most Idaho jurisdictions follow the IRC limit of two roof layers: if your house already has two layers of shingles, the job is a full tear-off, not a recover (IRC R908.3.1.1).
• Budget about $125–$325 for the permit in Idaho (our planning average is about $200). Fees are set by each city or county — some charge a flat fee, others a share of the job value — so check your local building department; the contractor normally pulls the permit and passes the fee through.

Codes are adopted and amended locally, so check your local building department before you sign. Sources: ICC International Residential Code 2021, Chapter 9 (R905.1.2 ice barrier, R908.3.1.1 recover limits).

How to get the best price in Idaho

1. Get 3 quotes — written and itemized.
2. Confirm the contractor pulls the permit (about $125–$325; your building department sets the fee).
3. Ask about Class 4 impact-rated shingles for an insurance discount.
4. Schedule late winter / early spring to lock in the lowest seasonal rates.

How Idaho compares with neighbouring states

Architectural shingles run $420 – $600 per square installed in Idaho. Across the state line the same roof is priced at: Washington $500 – $720 per square, Oregon $470 – $680 per square, Nevada $440 – $630 per square, Utah $430 – $620 per square, Wyoming $390 – $560 per square, Montana $430 – $620 per square. A contractor based over the border prices from their own labour market, so on a job near the line it is worth getting one quote from each side.
